IMPROVEMENT IN cLEvisEs.

Speciiication forming part of Letters Patent No. l 48,4345, dated March 10, 1874.; application filed August 19, 1873.

To all whom it may concern Be it known that I, JAMES H. ARNOLD, of the city of Louisville, county of Jefferson and State of Kentucky, have invented a certain new and useful Improvement in Plow-Clevises, of which the following is a specification:

The nature of this my invention consists in a clevis, the principal part of which is made somewhat similar to those now in common use, except that it is provided with additional attachment draft-hooks above and below the beam, for the purpose of setting the plow so as to merely skim the surface of the ground, if necessary, or of converting it into a subsoilplow, when desired, by simply changing the draft attachment from the hook above tothe one below, which can easily be done without removing the clevis from the beam. The abovevnamed draft-hooks are each provided with a drop-link to prevent the draft-ring from being detached in turning or otherwise.l

The object of this my invention is to provide a clevis that will be cheap, durable, and simple in construction, and by which the plow may be regulated to any required depth by simply changing the draft-link from one hook to the other, which can easily be done without removing` the clevis `from the beam.

The drawing is a perspective View of the clevis, showing the draft-hooks above and be= low the beam.

In the drawing, A is the clevis, and B is the pin or winch, by which itis fastened to the beam, all of which are made of metal. C C are the draft-hooks above and below the beam. D D are the drop-links, all of which are made as shown in the drawing. These links are inA tended to be used to prevent the draft ring or link from being detached in turning.

Having thus described the drawing, what I claim as new, and desire to secure by Letters Patent, is

The draft-hooks G C, with their drop-links D D, as above described, in combination withthe clevis A and pin B, when arranged, constructed, and operated substantially as and for the purpose set forth.
